, Application :filed May 19, 1917. Serial No..` 169,668..

To all whom it may concern:

Be it known that I,"WALTER LANE, a citizen ofthe United States, residingat Holland, Michigan, have invented certain new and useful Improvementsin Pneumatics and Connections for Pneumatic Piano-Players, of which thefollowing is a specification.

This invention relates to improvements in pneumatics and theirconnections for pneumatic piano players.

The objects of the inventions are,

First, to provide a construction of pneumatic which is readilydetachable.

Second, to provide a construction of pneumatic in which the valveconnection to they pneumatic structure.

Third, to provide improved detachable connections from the pneumaticstothe piano action.

Fourth, to provide improved adjustable connections from the pneumaticsto the piano action.

Further objects, and objectsv relating to details and economiesofconstruction and operation will definitely appear :from the detailedvdescription to follow.

I accomplishv the objects of my invention by the devices and meansdescribed in the following specification.. The invention is clearlydefined in the claims.

'A structure showing a preferred embodiment of my invention isclearly'illu'strated in the accompanyingdrawing, forming a part of thisspecification, in which: n f

Figure I is a longitudinal section through the pneumatic andsupportingparta showing the connection thereof to the suction chestand-showing how it is connected to the action.

Fig. II is a perspective view of the pneumatics attached to the suctionchest, the suction chest being broken away, showing the openingsregistering with the openings in the pneumatics.

In the drawings, similar numerals of reierence refer to similar partsthroughout the several views.

Considering the numbered parts of the drawing, 1 represents generally apneumatic of the bellows type comprising a relatively fixed and movablemember. The movable member of the pneumatic is provided with aprojecting iinger 2 having a longitudinal slot 2 therein for connectionto the player litters. 3 is the pneumatic valve which is yis throughsolid parts of the under control through the suction tube 4,controlled'` by the perforated sheet at the tracker bar to which thetube 5 is connected, these parts being of the usual construction andtheir details forming no part of this construction they are not furtherillustrated.

"The valve casing 3 is fixed to the upper member of the pneumatic. Thepneumatic is detachably secured to the'suction chest 6 so that it may beremoved therefrom and from the pneumatic of the action from the front ofthe suction chest. The valve casing is so mounted on the pneumatic thatit may be disposed against the front side of the suctionchest with itsports registering therewith as shown in the drawing.

I provide the clamp or clip comprising a `bar-like clamp member 7disposed to rest on the chest 6 and a lever-like clip member 8 pivotedto the rear end of the member 7 and provided'with a toe 8 engaging withthe keeper 9 mountedon the pneinnatic. The clip member 7 is providedwith the lug 7 depending in front of the lug 11 on the valve casing sothat the set screw 10` carried by the lug 7 may be adjusted to clamp the'parts together. This simple arrangement provides an effective supportand clamping means for the lpneumatic and'one which permits attachmentto or removal from the suction chest without disturbing other parts.

The finger 2 of the pneumatic is designed to receive the stem 13 of thelifter or piano action actuating member 12. This stem 13 is providedwith adjustable stops 14 coacting ywith the finger 2 and isextendedthrough a guide 1S common to all of the stems. The guide 18 issuitably supported on the framework. TheV adjustable screw 15 at theupper end of the lifter or actuating member 12 contacts with the pianoaction. As the details of the action parts form no part of thisinvention, as will be readily understood, they are not describedherein.l

The actuating member 12 is supported and maintained in position by thehorizontally disposed link 16 pivoted at one end to a suitable supportand at the other to the actuating member. An adjustable stop 17 isprovided to limit the upward movement of the actuating member. To limitthe throw of the valve 3, an adjustable sleeve like stop 19 is providedfor the port 20. This stop may be adjusted to compensate for varyingthickness of leather used to face the valves.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

l. In a structure of the class described, the combination with a suctionchest having a port in its front side, of a pneumatic comprising arelatively iXed member disposed below said chest and having thereon aforwardly facing keeper disposed at the rear of said chest, a valvecasing secured to said pneumatic and disposed on the front side of saidchest and provided with a port registering with the said port thereofand with an upwardly projecting lug, a clip bar disposed to rest on saidchest and provided with a lug depending in front of said lug on saidvalve casing, a keeper engaging member pivoted on said clip bar toengage said keeper and the rear side oi said chest, and screw disposedthrough said lug on said clip bar to engage said valve casing lug,whereby said pneumatic is detachably secured to said suction chest.

2; Ina structure ot the class described, the combination with a suctionchest having a port in its front side, of a pneumatic comprising arelatively fixed member disposed below said chest and having thereon akeeper, a valve casing secured to said pneumatic and disposed on thefront side of said chest and provided with a p rt registering with thesaid port thereof, a clip bar disposed to rest on said chest, a keeperengaging member pivoted on said clip bar to engage said keeper and therear side of said chest, and a clamping screw disposed on said clipbai-to en-4 gage said valve casing whereby said pneumatic is detachablysecured to said suction chest.

3. In a structure of the class described, the combination of a suctionchest, oi' a pneumatic disposed below said chest and provided with avalve casing disposed against the front side thereof, said pneumaticbeing provided with a keeper disposed at the rear of said chest, and asecuring means for said pneumatic comprising a pair of pivotallyconnected members one of which is disposed to engage said keeper and therear side of said chest and the other to engage the top of saidchest,and a clamping screw on the second of said members engaging saidvalve casing.

4. In a structure of the class described, the combination with a suctionchest, of a pneumatic provided with a keeper and having a valve casingdisposed against said chest, and aV securing means i'or said pneumaticcomprising a pair of pivotally connected members disposed to engage saidchest, one oi' said members engaging said keeper and the other beingprovided with a clamping screw engaging said valve casing.

5. In a structure of the class described, the combination with a suctionchest ol' a pneumatic, a valve casing rigidly secured to the uppermember thereof, and having an upwardly projecting lug, a keeper on thesaid member, a clamp comprising a horizontal member adapted to contactwith the upper side of the suction chest, and a lever member with aprojecting toe to engage said keeper, and a downwardly depending lug onthe horizontal member with a set screw 'for engaging the lug on thevalve casing, coacting ioigthe purpose speciiied.

6. In a structure or' the class described, the combination with asuction chest o'l' a pneumatic, a valve casing rigidly secured to oneside of said pneumatic, a clamp comprising a member engaging one side oia suction chest and a Vlever pivoted to said member engaging the sideor' the suction chest opposite the valve casing and a keeper on thepneumatic, all coacting Jfor the purpose specified.

In witness whereof, I have hereunto set my hand and seal in the presenceof two witnesses.
